用image模組更直接，可以用getpixel獲得畫素值，給你個例子吧。

01.#!/usr/bin/env python

02.import Image

03.import sys

04.im = Image.open(sys.argv[1])

05.width = im.size[0]

06.height = im.size[1]

07.print "/* width:%d */"%(width)

08.print "/* height:%d */"%(height)

09.count = 0

10.for h in range(0, height):

11. for w in range(0, width):

12. pixel = im.getpixel((w, h))

13. for i in range(0,3):

14. count = (count+1)%16

15. if (count == 0):

16. print "0x%02x,/n"%(pixel[i]),

17. else:

18. print "0x%02x,"%(pixel[i]),
